Great Britain June 2 Claims. (01. 15-158) This invention relates to dust removing devices and is herein disclosed as embodied in a vacuum cleaning brush. while the illustrated brush may be employed for a variety of purposes it has proved particulafly satisfactory for removing the fine deposit of dust which collects upon shoes after the shoes have been subjected to a buifing operation. Notwithstanding the fact that buffing machines are usually equipped with suc-.. tion dust hoods, it is impossible toprevent some dust settling upon the shoe, and attempts to wipe or brush this dust off .by ordinary means are frequently unsatisfactory and frequently result in leaving a disfiguring mark upon the shoe. J 1 This application is a division of our copending application Serial No. 674,565 which resulted in United States Letters Patent. No; 2,008,797, granted July 23, 1935.

It is an object of the present invention to provide a device for removing dust, for example the fine dust which, as above mentioned, settles upon shoes in the course of bufing operations.

The device herein illustrated consists of a vacuum cleaning brush having two setsof bristles, one for light colored shoes and one for dark colored shoes, so arranged that when either set of bristles is moved into operative position the interior of that portion of the brush is connected with a suction system to remove the dust which is loos- Y ened by the bristles. In the illustrated construction, the brush may be moved an inoperative position wherein both portions of the brush are closed to the*'suction system, thereby conserving the draft when the brushis not in use. The features of the invention will be best understood from the following description of the' preferred embodiment thereof, selected for purposes of illustration and shown in the accompanying drawing, in which I Fig. 1 is a perspective view of the improved brush,

view of the brush Fig. 21s a cross sectional shown in Fig. 1;

upon the frame I0, and which has an outlet open- Fig. 3 is a view in longitudinal section'of the At each end of the head 96 the bearing members no and I32 are continuous with each other to form a complete cylinder. Inasmuch as an important use of'this brush consists in the removal of dust which settles upon shoes in the course of bufilng operations, it is desirable to mount the brush either on or in close proximity to a bufiing machine. Accordingly, the illustrated brush is shown in Fig. 4 as mountedupon such a machine. The frame portion of the machine is shown fragmentally in Fig. 4, and is identified by the numeral I0. For a complete disclosure of this machine, reference may be had to our copending application above mentioned. Supported upon the frame I0 is a large pan 40 for receiving dust from one or more buiflng tools (not shown). The suction tube 98 has an elbow-shaped extension which is secured to an end of the pan 40. The elbow ofthe tube 98 is connected by a conduit I00 to a'suction conduit III which leads to the intake of an exhaust blower 44 which is supported ing 45. The suction conduit I0 may be connected to one or more suction dust hoods (not shown). The head 96 is provided with two hollow extensions I02 and I04'which, in the illustrated construction, are integral with the bearing members I30 and I32. The bearing members I30 and I32 do not extend across the interior of the extensions I02 and I04. The extension I02 has a portion I03 of increased width adjacent to the closed end 99 of'the head 96 and the extension w I04 has a similar portion I05 of increased width adjacent to-the closed end 99. The outer ends of each of these extensions are open and are provided with bristles I06. As shown in- Fig. 1, the open end of theextension I02 is in the-form of two rectangles arranged in the shape of the letter T. The end of the widerportion I03 constitutes the cross bar of the T. The open end oi'the extension 104 is similarly shaped. The bristles at the 40 outer ends of the extensions extend around each of the-rectangles, and the stem of each T has a bridge extending lengthwise along its center and carrying a double row of bristles. Three openings I00, m and H2, respectively, are formed in the wall of the tube 98. Mountedin a lug'I I4 extending from the head 96 is a lock-p ing pin H9 which engages one or. another of the openings I00, Band 2 to secure the head in one or three given positions. The pin H0 is 50 40 thereupon carried away by the current or air the interior oi'the tube 90 communicates with the interior of the brush extension I02 through the opening I which is elongated to provide an air passage, the openings I and II 2 beingonly of suflicient size to receive the pin H6. The opening IIO, which constitutes an air inlet opening, is thus relatively large compared-to the openings I08 and H2. The bristles upon the brush extension I02 are intended to be used upon shoes of relatively dark color. When it is desired to clean relatively light shoes, the bristles oi.

the brush extension I04 are employed. It will be evident that the use of two diflerent sets of bristles will serve to avoid the transfer of color from dark to light shoes. In utilizing the extension I04, the head 901s rotated 130 from the position shown in Fig. 2. The ope 0 will then register with. the interior of the extension IOLand the pin II6 will enter the opening II 2.

When neither ofthe brush extensions is to be used the head 901s rotated 90 in a clockwise direction, The pin IIG will then engage'the opening H0 and thus maintain the brush'members in inoperative position. with the inlet opening IIO closedby the cylindrical bearing memberl'30.

It will be observed that the opening I I0 serves both to admit air into the duct 98 and to engage tion or the shoe against the bristles of the brush.

which tends to loosen, the dust. The dust is through the suction system.

- Having d cribed our inven on, wha ecleini as new and desire to secure by Letters Patent oi the United States is: 1

1. A tool for removing dust from shoes comprising a tubular suction duct having an inlet opening in its wall, a head having acylindrical portion whereby the head is mounted for rotary movement upon said duct and having also two hollow extensions the outer ends of which extenslons are open and the inner ends of which are adapted to communicate, one at a time, with the inlet opening in said suction duct, the cylindrical portion oi.said head being positioned between said extensions and operating to close said air inlet opening when neither extension is in operative position, cleaning means mounted at the outer ends 'of said 'extensions and means for locking said head alternatively in positions such that the desired one of said extensions communicates with said inlet opening and also in an inoperative position in which the cylindrical portion of thehead closes the inlet opening. 2.
